We review our recent studies on ultrafast vibrational dynamics of adsorbates on metal surfaces under the influence of high electron temperature induced by femtosecond laser excitation. Energy transfer dynamics between substrate electron and adsorbate vibrations mediated by nonadiabatic coupling has been investigated by time-resolved nonlinear optical spectroscopy including infrared-visible sum frequency generation and second harmonic generation. In particular, we focus upon CO and alkali metal atoms on Pt(111) and Cu(111) surfaces.
